For Clan Castle donations, ask for Witches, Wizards and Archers for troops and Earthquake Spells or Poison Spells (depending on preference and league) for spells. If you are a Town Hall 10 using this strategy, replace Witches with Wizards. If you are a Town Hall 9 using this strategy, remove both Witches and add a Wizard to comply with housing restrictions. To cut down on Elixir, consider replacing Wizards with Archers. To cut down on Dark Elixir, replacing Witches with Wizards or Valkyries is an option, but I don't recommend it.

Unlike other Earthquake Spell strategies, drop your Earthquake Spells on powerful buildings (Multi-Target Inferno Tower>Eagle Artillery>Single-Target Inferno Tower>X-Bow>Wizard Tower). Make sure to drop at least one on an outside compartment to create an opening for your troops. It may be wise to save an Earthquake Spell for the Hidden Teslas if there is a large empty compartment that could fit four Hidden Teslas.
Drop your Giants near a wall that has been weakened by your Earthquake Spells.
Once your Giants are drawing fire, place two Wallbreakers behind the giants to destroy the walls.
Once you are inside the base, place your Valkyries, Clan Castle*, Barbarian King, Archer Queen and Grand Warden behind the Giants and the Wizards around the outside, clearing up buildings.
Begin placing your Witches once they have a defense-free path towards the center of the base.
Place Wallbreakers, Heal Spells and Poison Spell as needed to keep your troops moving towards the center.
Once you are near the center, place Wallbreakers to break through to the center compartment.
Once in the center, drop a Rage Spell on your troops to allow them to take out the Inferno Towers and Town Hall quickly.
Once through the center, simply allow your troops to take out the rest of the base.
*- If your Clan Castle contains Golems or Giants by mistake, drop it with the Giants instead of the Valkyries.
In conclusion, this is a fun attack strategy that mixes it up from your standard Lavaloon or GoWiPe. I hope this strategy brings you both fun and success!
